Welcome to the forum- you are not alone and have come to the right place.
Glad to hear that you are working with a therapist to address anxiety/depression. There is often an emotional component to vaginismus. I’m not sure if you are still seeing your pelvic floor PT and it may be a good idea to have another session to help you move up in dilator size and help with your confidence. We at Maze treat both the physiological as well as the emotional components of vaginismus. It’s understandable that you have concerns getting into a relationship and explaining or not explaining to a potential partner. Vaginismus is curable and you are courageously working on it.
Keep us posted.
Stay safe and sound,
